Hacktivism

I am getting more interesting in the idea of hacktivism and the controversies surrounding it.  Before you ask, no, I haven't done any hacking or illegal computing of any kind.  As you may know from news reports, the two big-name groups are Anonymous and (the now-disbanded) LulzSec, who have done some work together under Operation AntiSec.  It seems to me that the attacks they carry out are not legal (see here, here, and, most fully, here), though I am often sympathetic to their rationales.  Using a variety of attacks, they have hit Sony (protesting the arrest of someone who had hacked them), MasterCard and PayPal (protesting their severing ties with WikiLeaks), and Arizona (protesting SB1070), among many others.  Their DDoS attacks use Low-Orbit Ion Cannon to attack other sites.  They have worried about being caught, and the eventual arrest of an alleged member after LulzSec called it quits led rapper Moses to pen this song.  And joining is easy.  But be warned: others will want to take you down of you get too involved.
